Value Chain Investigations on Four Colombian Palm Species = Investigaciones de las Cadenas de Valor de Cuatro Especies de Palmas Colombianas

Por: Natalia Valderrama | Fecha: 2011

In many cultures palms offer a vast number of products, especially Non-Timber-Forest Products (NTFPs), which have been traditionally used by indigenous and mestizo groups in Latin America. Some species have gone beyond the domestic use and their commercialization has reached local, national and international markets. Among the palm products that are widely commercialized in South America are palm heart (Euterpe oleracea), extracted from the young unfolded spear leaves of the palms, and the handicraft woven from fibers (Astrocaryum chambira, A. malybo and A. standleyanum), all extracted from the leaflets. In Colombia, these four palm species are economically important for the harvesting communities as well as for wholesalers and retailers. However, commercialization has been based on the extraction of raw material from wild palm stands up to the point that several palm species are threatened by developing markets for their products, and the need of income for the harvest communities and industry. The general objective of this thesis is to describe the value chains of palm products from E. oleracea, A. chambira, A. malybo and A. standleyanum in different Colombian regional markets, as well as national and international markets, and to analyze the economic importance, potentials and implications of this trade. Data on the four value chains was gathered through interviewing all actors of the value chain and revising the literature about the commercialization of these palm products. This study assesses the main actors or organizations in the commercialization chains, their specific activities, different routes to trade products, and how well the chains currently work by conducting a qualitative and quantitative value chain analysis.Major results involve particular dynamics and distributions of the profits along each value chain, as well as common aspects: the value chains are short, simple, the commercialization channels need to be strengthened, the scarcity of the raw material is a crucial constraint for the commercialization of the products. Unsustainable harvest practices are common. Moreover, the marketing potential of each group of palm products as well as promised target markets are characterized. The principal contribution of this thesis consists in shedding light on the current status of the value chains of these four palm species in Colombia, and proposing possible routes of development to strive for sustainability in each of the value chains analysed. Moreover, this study provides information about the economic importance of the palm products to the local communities and the need to upgrade the commercialization channels, products and communal incentives to assign equitable incomes along the chain.

The perceived usefulness of travel time and its implications on the study of travel demand : a study based on northern californian commuters

Por: Javier Ramírez Salgado | Fecha: 2013

In earlier decades, a number of authors have been looking at how commuters value the usefulness of travel time and at which point it is still considered to be a disutility to minimize. This document presents the results of a survey which was carried out on different transportation modes in Northern California. The results of this study show how the utility of travel time may change from one person to another, unveiling the latent relationship between several factors (i.e. Attitudinal factors, primary mode of transportation, age, gender, etc.) and what we consider the usefulness of travel time. This study included several considerations made from different approaches, including linear regression analysis and ordered probit models. The dependent variable was always considered to be the usefulness of travel time represented in the final survey by an ordinal variable. Moreover, the study comprised data segmentation (i.e. primary mode of transportation) which explained some conceptual differences between a pooled model and “active-passive” models. Finally, the outcome of this study shows how active travel modes (i.e. Car driving) are usually the most unattractive, for the reason that the possibility of engaging in different activities while traveling is very limited. Similarly, how the activity itself may change the perception of travel from a disutility to minimize to a transition or mostly useful time.

Robust and flexible planning of power system generation capacity

Por: Diego Mejía Giraldo | Fecha: 2013

The successful evolution of a power system is achieved when its future growth path is visualized. Visualizing and interpreting the future are crucial to understand the risks to which the power system is exposed. These are mostly caused by the interdependencies between the power system and other systems (e.g., transportation sector, fuels sector, industry, etc.); and the resulting uncertain environment where these systems perform. Then, the objectives of planning are to reduce the risks of uncertainties and to gain some control over the future by linking it with the past; otherwise risks might materialize in catastrophic consequences. In particular, motivated by the need of mitigating future risks in power systems, this work focuses on finding robust and flexible investment strategies in the generation capacity expansion planning problem under exposure to multiple uncertainties. They are present in different sources and types such as fuel costs, investment and operational costs, demand growth, renewables variability, transmission capacity, environmental policies, and regulation. The problem when considering multiple uncertainties is much harder, not only because the increased computational effort, but also because it is hard to model the combination of their occurrences in a single optimization problem. Since each uncertainty deserves special treatment, they are grouped into two categories. Those (categorical) uncertainties that really impact the portfolio investment decisions are classified as global; whereas those that quantitatively describe the intrinsic imperfect knowledge of the categorical are considered local uncertainties. So, to effectively account for robustness, defined as the ability to perform well under unforeseen situations, and flexibility, defined as the ability to adapt cost-efficiently to different situations, modern tools are illustrated and implemented in a computationally tractable manner, resulting in promising planning tools under uncertainty.

Relationship between Support for Innovation and Innovative Behaviour in Colombian employees = Relación entre el apoyo a la innovación y comportamiento innovador en empleados colombianos

Por: Lisseth Vanessa Gutiérrez González | Fecha: 2015

Abstract: This study reports findings of antecedent variables of innovative behaviour in Colombia. It tested the positive relationship between support for innovation and innovative behaviour of Colombian employees, as well as the patterns of association between educational attainment and innovative behaviour and the link between organisational size and innovative behaviour on Colombia employees. The study had a quantitative research strategy with a cross-sectional research design, with a final sample of 182 Colombian employees. Results indicate that one dimension of support for innovation – support for creativity, is positively correlated with Colombian employees’ innovative behaviour. Whereas, the other dimension of this scale had no correlation with innovative behaviour. Thus, findings on the link between these two variables (support for innovation and innovative behaviour) have some similarities and differences to previous studies. This highlights the importance of the Colombian national culture on the antecedent variables of innovation. Likewise, the two secondary antecedent variables of innovative behaviour had no association with Colombian employees’ innovative behaviour. Finally, this paper includes the scopes and limitations of the study and future research directions are also considered. Resumen: Este estudio reporta los resultados de variables antecedentes del comportamiento innovador en Colombia. Se estudió la correlación positiva entre el apoyo a la innovación y el comportamiento innovador en empleados colombianos, así como la relación entre nivel educativo y comportamiento innovador y la relación entre tamaño de la empresa y comportamiento innovador en empleados colombianos. Este estudio cuantitativo tuvo un diseño transversal con una muestra final de 182 empleados colombianos. Los resultados indican que una sola dimensión de apoyo a la innovación (apoyo a la creatividad), está correlacionada positivamente con el comportamiento innovador de empleados colombianos, mientras que la otra dimensión de ésta escala no tuvo ninguna correlación con el comportamiento innovador. Los hallazgos de la relación de estas dos variables (apoyo a la innovación y comportamiento innovador) poseen algunas similitudes y diferencias a estudios previos. Lo anterior permite destacar la importancia de la cultura nacional colombiana en lo concerniente a variables antecedentes de la innovación. Del mismo modo, las otras dos variables antecedentes del comportamiento innovador no tuvieron ninguna correlación con el comportamiento innovador de los empleados colombianos. Finalmente este manuscrito incluye los alcances y limitaciones del estudio y también se abordan sugerencias para futuras investigaciones.

Context Management and Self-Adaptivity for Situation-Aware Smart Software Systems = Administración de Contexto y Auto-Adaptación para Sistemas de Software Inteligentes y Sensibles a las Situaciones

Por: Norha Milena Villegas Machado | Fecha: 2013

Our society is increasingly demanding situation-aware smarter software (SASS) systems, whose goals change over time and depend on context situations. A system with such properties must sense their dynamic environment and respond to changes quickly, accurately, and reliably, that is, to be context-aware and self-adaptive. The problem addressed in this dissertation is the dynamic management of context information to improve the relevance of SASS systems' context-aware capabilities with respect to changes in their requirements and execution environment. Therefore, this dissertation focuses on the investigation of dynamic context management and self-adaptivity to: (i) improve context-awareness and exploit context information to enhance quality of user experience in SASS systems, and (ii) improve the dynamic capabilities of self-adaptivity in SASS systems. Context-awareness and self-adaptivity pose significant challenges for the engineering of SASS systems. Regarding context-awareness, the first challenge addressed is the impossibility of fully specifying environmental entities and the corresponding monitoring requirements at design-time. The second challenge arises from the continuous evolution of monitoring requirements due to changes in the system caused by self-adaptation. As a result, context monitoring strategies must be modeled and managed in such a way that they support the addition and deletion of context types and monitoring conditions at runtime. Concerning self-adaptivity, the third challenge is to control the dynamicity of adaptation goals, adaptation mechanisms, and monitoring infrastructures, and the way they affect each other in the adaptation process. This is to preserve the effectiveness of context monitoring requirements and thus self-adaptation. The fourth challenge, related also to self-adaptivity concerns the assessment of adaptation mechanisms at runtime to prevent undesirable system states as a result of self-adaptation.

Refutación del mensage del Sr. Aquileo Parra, Ex-presidente de Colombia al Congreso de 1878

Por: Recaredo De Villa | Fecha: 1880

En 1878, el entonces presidente Aquileo Parra dirigió un discurso al Congreso Nacional, en el que justificaba la guerra que, durante su gobierno, se había hecho contra los Estados Soberanos de Antioquia y Tolima. Como contraparte, y con el ánimo de refutar los argumentos de Parra, el gobernador de la provincia de Antioquia, Recaredo de Villa, elaboró un informe en el que acusó a Parra de calumnioso e injusto. Este documento, publicado en 1880, contiene el informe de refutaciones que Villa presentó al congreso en el mismo año, así como una serie de cartas intercambiadas entre Parra y Villa respecto a las acusaciones que le hizo.
